I used the plow as an example in a list of things to illustrate the varied information you need to verify things and to illustrate that you can't simply do research on everything. Maybe you missed that?

You can't trust the company making the lead test kits any more than you can trust General Mills. How would you know the tests are real, especially without a regulating body to verify that stuff?

What if it isn't General Mills and Cheerios? Do you test everything that comes in contact with your food? What is in their plows?

You aren't just testing the Cheerios. You are just choosing to trust one thing instead of another and you simply cannot have time to test all of the Cheerios in addition to the other things in life.

To continue with your example:

Lead tests, and lead-testing labs, stay around by being accurate, reproducible science.

General Mills stays around by putting out wholesome commercials so you buy their slop.

My family and I could eat a total of 10 food products.
